Description

Technical Field

[0001] This utility model relates to the field of e-book production equipment technology, and in particular to an e-book motherboard function testing device. Background Technology

[0002] Functional testing of e-reader PCBA boards requires testing multiple sets of voltages, charging currents, sleep currents, shutdown currents, and simulated screen wake-up tests. The traditional method involves manually testing each contact with voltmeters and ammeters, which suffers from poor contact, excessive manual work, fatigue, and low efficiency. Furthermore, relying on visual inspection to manually determine whether test values ​​are within specifications results in numerous testing actions, fatigue, low efficiency, and a high rate of missed defects, impacting customer satisfaction. Traditional methods involve excessive manual work, fatigue, and are prone to omissions; test results cannot be automatically recorded, and are particularly inefficient and labor-intensive. Utility Model Content

The programmable power supply provides different voltages and currents required for testing under the control of the test PC. Different voltage and current output terminals of the programmable power supply are respectively connected to the motherboard test fixture. The motherboard test fixture has two or more test stations, each corresponding to one e-book motherboard. Fixture probes are driven to rise and fall by a quick-clamping mechanism to contact or separate from the e-book motherboard. Each fixture probe is electrically connected to the relay switching tool board via a signal connection line. The relay switching tool board has a corresponding relay control circuit for each relay switch to control the switching operation of each relay switch. The multimeter is electrically connected to the voltage output terminal of the e-book motherboard and detects the output voltage of the e-book motherboard.

[0006] Furthermore, the motherboard test fixture is electrically connected to the test PC via a USB to TTL UART communication card.

[0007] Furthermore, the motherboard test fixture also includes a fixture base, on which corresponding positioning posts and connection probes are provided for the e-book motherboard, and the e-book motherboard can be detachably fixed on the fixture base.

[0008] Furthermore, the e-book motherboard has a barcode containing the motherboard's serial number; the testing device also includes a barcode scanner, which is connected to the testing PC and used to read the barcode.

[0009] Furthermore, the test PC is an industrial computer, and the digital multimeter used is a six-and-a-half-digit digital multimeter.

[0010] This invention employs the above technical solutions, achieving high accuracy in FT testing results, simplifying testing procedures, and significantly reducing manual operations. Using this device, simply scan the barcode, place the e-book motherboard into the motherboard testing fixture, and control the corresponding test station's fixture probes to press down via a relay switching tool board. The test PC acquires the test results from the motherboard testing fixture, thus realizing e-book motherboard testing and outputting the results. This invention allows one person to operate four workstations, greatly improving efficiency, facilitating operation, and automatically recording and tracking product test logs.
